GPT and type 1 diabetes mellitus: Two studies applied imaging after preselection in the type 1 diabetes population: (1) Leeds et al performed ultrasound only in 17 patients with persistently elevated alanine aminotransferase (ALT) levels higher than 50 IU/L; (2) Marjot et al performed TE only in 11 patients with an intermediate or high risk Fib-4 score and subsequently calculated an extrapolated prevalence rate in their total type 1 diabetes population (33, 36).
